About

This fast-finishing autoflower comes from our own Frostbanger Auto F4 (winner of The Strongest Autoflower title at the Autoflower World Cup) crossed with Sundae Thumper (Mephisto Genetics; Best Hybrid at the American Autoflowe Cup). It is built for efficiency and visual appeal, completing its full cycle in just 70–75 days from seed to harvest. Plants typically reach 60–100 cm, making it an excellent choice for growers working with limited space or seeking quick, reliable turnovers.

During testing, two distinct phenotypes were observed, both sharing the same terpene profile but differing in coloration. The first phenotype displays predominantly green buds with subtle purple or pink accents, while the foliage remains green throughout the entire cycle. The second phenotype introduces a more dramatic contrast: buds remain mostly green with purple highlights, but the leaves develop deep black-ish tones, giving the plant a striking, premium appearance that stands out in any grow room.

Despite these visual differences, both phenotypes deliver a consistent aromatic profile. Expect a sweet, spicy, and notably fresh scent, combining a clean, uplifting character with a subtle depth that becomes more pronounced as the buds mature.

This variety offers a balanced combination of speed, uniform structure, and aesthetic diversity, making it well-suited for both home growers and those looking to maximize production cycles without compromising on quality or bag appeal.
